Sharing is caring!

Adults

In adult life the main bar to exercise is the lack of time resulting from gainful employment and/or bringing up the kids. For you, the working person/parent, the most important incentive to exercise must be an understanding of just how vital this is to your future health, happiness and longevity. If you have not cottoned on to that by now you have not been concentrating – start again and read my Blog more thoroughly!

Medical advice

Encouraging people to take more exercise is a difficult task. Healthcare professionals can, but usually don’t, target appropriate patients.  Advice during the consultation is seldom given. A US study of consultations for diabetes or hypertension showed that exercise was recommended on only one sixth of occasions. Even when advice is given it is largely ineffective. A recent meta-analysis of trials of physical activity promotion in primary care did find a slight increase in self-reported physical activity at 12 months but those trials which also measured physical fitness showed no significant increase.

Exercise on prescription

There are many schemes which encourage GPs to prescribe exercise and most local authorities have systems for “exercise on prescription”. The idea is that the GP “prescribes” a course of exercise at the local Sports Centre. The individual has an initial assessment followed by a course of exercise of around ten weeks at a cost somewhat lower than that charged to the general public. At the end of the course the individual is encouraged to continue to attend the Sports Centre at the usual rate.

Exercise training and physical activity are not part of the usual medical student’s curriculum and this may explain why the level of referral to such schemes is extremely low. The uptake and completion of prescribed exercise programmes is even lower. Analysis of a number of these schemes shows that such referral systems do not increase physical fitness, health related quality of life or exercise habit in the longer term.  The idea of exercise on prescription sounds great but more attention needs to be paid to barriers to attendance and continued adherence. Some of the factors which have been identified are poor organisation of the scheme, inconvenient opening hours, poor social support and exercise leaders lacking motivational skills.

“Selling” exercise

Exercise schemes can have some effect but only if combined with a lot of extra input to encourage the individual and nurture the changed attitudes and behaviour which are required. A New Zealand study enrolled 1089 women aged 40–74 into a controlled trial of exercise referral and achieved a modest increase in exercising rate in the treated groups at two years. The intervention included initial motivational interviewing, regular follow-up telephone calls (a total of 75 minutes per patient) and a home visit at six months. Even with this level of input the apparent increased exercise was not associated with improved clinical outcomes but unfortunately was associated with an increased risk of falls and injuries.

The QOF scheme

Prescribing exercise is not part of the thinking of most general practitioners. They have quite enough on their plates and there is no reward for sending the patient to a sporting facility. This is unlike the situation for many aspects of preventive medicine in general practice.

The system called the Quality and Outcomes Framework (QOF)  decides a good proportion of the GP’s income. The GP is rewarded for including patients on the obesity register, for getting their blood pressure or blood sugar to an acceptable level and for prescribing a number drugs which the NHS  recommends. Payment is also made for referral to various agencies for support and education. However among hundreds of indicators there is only one related to exercise and that is the number of patients with COPD referred to pulmonary rehabilitation. Otherwise there is no incentive at all for screening for physical activity or for  encouraging physical activity.

Perhaps if referral to an exercise programme were included in the QOF we might see a benefit for both the individual and the nation as a whole?

Exercise is medicine

Encouraging the population to take exercise needs the commitment of doctors, who should regard exercise as a medicine, as effective a weapon against disease as any drug. The time may be coming for the life style approach. As the BMJ put it “Is lifestyle medicine emerging as a new medical specialty?”  The British Society of Lifestyle Medicine was founded in 2016 and this approach is now being adopted by some medical schools, including Cambridge University. Ideally lifestyle medicine should not need a label of its own but will become an integral to the delivery of health care.  In its delivery the medical profession needs to be backed up by political action to make physical activity promotion and facilitation key goals in their public health strategy.
